There's an "average size of humans has increased" joke in here somewhere - both height and girth.
And I do agree to a point. We're very happy to have increasing numbers of users so we can afford to do things like contracting the excellent developer who's working on JMAP support for Calendars in Cyrus IMAP at the moment, as well as hiring people to add new features or improve existing ones.
We do try to stay at a point where we can run comfortably on 50% of our hardware, so we can shut down half our machines at once for maintenance. Redundancy certainly helps - we've blogged a few times about how good it is to be able to shut down any one machine with only a few minutes' warning to move active users off it.
I'm certainly looking forward to spending time again on what I wanted to be doing (Cyrus IMAPd improvements at the moment) rather than battling a DDoS!
